Axiom Home Page Forums General Discussion Home Theater Oppo BDP-83 on the way.

On the BDP-83, if you set HDMI to bitstream then the dedicated two-channel analog output (which have better DACs than the 7.1 analog outputs) will only use the L and R channels of a multichannel SACD. Setting HDMI output to LPCM will allow proper downmixing of multichannel SACD to two channels. Allowing decoding within the player will also allow you to listen to secondary audio in blu-ray discs; bitstream will not allow secondary audio. However, you may not want secondary audio as it is apparently not in a high res audio format and can potentially decrease audio quality if you allow it to be passed. You can turn off secondary audio at the disc level or player level. The FAQ and manual has good information on all of this.

Thanks House and hifi. I don't have any SACD's YET, and I don't know what you mean by "secondary audio". Remember, I've never even played a Blu-ray before.

Ooh, they already shipped it. I paid for 2-day shipping because I'm impatient. I can't wait.

And yet, wait you will.

Wheelz,
Since you have a Denon 3808 that can decode all codes/and don't need SACD support, you can bitstream everything.

*sigh* Yeah, I will. And what's worse is the Signature Required may trip me up. I don't know if I can have anyone waiting around for it for me. Here's hoping.

Yoink!

Never tripped me and never will...

Hey Wheelz, this is from nickboros' link:

Secondary Audio is an optional yak-track that goes with the Blu-ray Picture-in-Picture (PIP) feature. It is mixed in with the main audio so both tracks are audible together. Like BD-Live and excessively complicated menus, it is a marketing-driven Blu-ray feature that no one ever asked for.

I'm wondering if the BDP-83 has a limitation which the PS3 does not.

Throughout the tech talk thread on AVS, it has been mentioned that if the Oppo plays secondary audio it will be mixed with the core, or lossy track.

I can't say for sure what the PS3 does, but every indication points to it mixing with the full lossless steam.
